Guys I am a newbie to this. Do I need new hands and stem? What else would I need to make this swap in a submariner rep?

I doubt it would be worth the trouble. In a closed caseback watch, no one's going to see the difference, and unless the diameter and stem height and overall height of the movement are identical, it likely requires some machining of the case.

Unless you're a hobbyist with the right tools and skills and a desire to do it, it would be far easier to just buy a new watch with the Rolex clone movement. Most watches with 2813 aren't high end reps (although some can be modified to be), so you're putting a lot of effort into a mediocre watch.

Is there a form fit function replacement for 2813A? I paid $180 for the watch. It’s a decent rep but. Never worked from the beginning. It runs fine until you wear it and then it stops sporadically. If I wind it and lay it on the counter, it will perfectly until the charge runs out

You can get a new 2813 movement on AliX for $20 or less. I believe the Miyota (Citizen) 8215 is a close fit, but depending on the watch, it's either drop in or requires some modification.

2813 movements, generally speaking aren't known to be long lasting. Some have found they will run well with a service, but the ones they tend to throw into reps are often the lowest end of the quality spectrum.

Personally, if you like the watch, I'd recommend picking up a 2813 from Ali Express and learning to swap it in (or have a watchmaker do it and service it at the same time).

The 2813 is generally a decent budget movement, usually reliable with design based on the miyota 8215 adding a hacking feature. As said, you can pick up one for $20 or so and have it installed. Figure you're looking at $50 to 100 for a watchsmith to install it. It's your call if worth it, but I wouldn't bother. If you feel adventurous, you can swap it in yourself.

Totally agree with the others. The miyota 8215 is the solution to your problem. However I suggest you snag something with a better movement. If you’re budget minded get something with a 2824 or 2836 movement. There’s some really good a2824 and 2836 reps and they could last you a decade or more. Regardless when it dies you can have it swapped out with a sellita sw200 Swiss that’ll last you many years.

An ETA might not be a direct swap, depending on the case.

Apple to apple, just swop the 2813 with another 2813.

Sorry if I wasn’t clear enough about it. the miyota 8215 is the direct swap with the OP’s 2813. The sellita sw200 is the direct swap for the a2824 found in slightly better reps. Very unlikely there’s any eta reps since swatch has tightened down on who gets their movements. There’s just eta clones unless you buy a complete watch.

this is a rabbit hole. I warn you 😅

Those two movements won't swap.

8215 indeed is the more robust option vs 2813 the easiest/cheapest. BUT the seconds post is fragile like glass.

If you are starting out from zero, you will need quite a few tools, new hands and cut the dial feet if 8215.

Now if you are keen in getting into modding or even just acquiring the skills, it's fine. Go for it.

But if your intent is to DIY on the cheap, that's a bad idea. You will end up spending quite some money learning and a lot of frustration. assuming you don't break something 😅

Buy a VSF and be happy.

Okay, sounds like you guys know waaaaay more about this than I do. So if I go to Ali express and order a 2813a like the one that’s in it now, it should fit no problem. Any particular store on Ali Express you trust?

No Chinese new year delays.



If you want to save a couple of dollars and don't mind waiting a month or so, there's a number of listings on eBay, AliExpress, etc. here's one example

What about a Mingzhu DG2813? Will this work in my sub rep?

Seriously man,
think about this again.
While it's not that hard, it's not trivial either.
The seconds hand on a 2813 is a bitch

You will spend money in tools with no guarantee of result, for a watch that's not worth it.

@Karbon74 has given you pearls of wisdom, a couple of times. If you’re dead-set on the DIY route I suggest you take a closer look at the actual parts and not pictures of them. Get you a set of screwdrivers and tear into your busted movement if you want and get a taste of it, I doubt you’ll hurt anything. Just saying

This is not an easy thing to do as a first timer-DIY project IMO. Plus, you are going to need to buy at least a small set of watchmaker tools. If you are wanting to learn and start doing your own mods, then maybe I get it. Otherwise, if this is your only planned DIY project, just buy a VSF sub, either from a TD ($550-ish) or M2M ($450 or less). You'll get a solid Rolex clone movement, and you'll have a very close to 1:1 clone out-of-the-box. Then, you can mod/add gen parts to your VSF sub if you want to. This is much better use of your money as it will hold it's value (or minimal drop in value) if you ever decide to sell the watch M2M down the road. Just my two cents of course...
